# TypeScript Generics Explained
Generics in TypeScript allow you to create reusable and type-safe components. Here’s a simple example:
function identity<T>(arg: T): T { return arg}
console.log(identity<string>('Hello'))console.log(identity<number>(42))Generics can also be used with classes and interfaces:
class Box<T> { private content: T
constructor(content: T) { this.content = content }
getContent(): T { return this.content }}
const stringBox = new Box<string>('TypeScript')console.log(stringBox.getContent())Generics are a powerful feature that can make your TypeScript code more flexible and maintainable.
